At approximately 42:19 mark into Rob Bell’s interview with Caleb Wilde (Caleb Wilde is a Funeral Director), this happens:

Caleb: I think that grief is worship <…>  That takes the shame out of it.  So many people are just: “Oh, why am I not at closure yet, and why haven’t I processed through this linear grief work yet?  I should be done by now!”

But I think grief is a form of worship.  <…>  Closure is a myth.  It doesn’t happen the way we want it to happen.  It’s messy.  And the person who has died is there.  As long as you love someone you will be grieving.
